| Abstract | 21例の大動脈基部置換術では, 当初は機械弁を使用し, 左右冠動脈も人工血管でinterposeし, 瘤壁で被覆した. 今では被覆は止めており, 冠動脈もボタン状にくりぬいて再建している. さらに65歳以上にStentless Xenograftを用いて, 機械弁の場合と同様にマットレス縫合で固定している. この方法の変遷を評価したい. 男女比は17:4, 平均年齢50.3±18.2歳. 瘤壁で被覆した群としなかった群の比較, 機械弁と生体弁使用群の比較を行った. 瘤壁による被覆をしなかった方が大動脈遮断時間は永いが, 出血量は少なく早く退院できた. また生体弁使用ではより高齢者でありながら, 早期に退院できた. 生体弁による現在の方法は早期退院ということで評価できた. |

| Abstract | As an aortic root replacement therapy to annuloaortic ectasia we now perform a simple button anastomosis as coronary reconstruction, and no more wrapping technique with aneurysm. We also select Stentless Xenograft (Free Style Valve) as a prosthetic valve conduit to the older age over 65 years old and to the prohibited patients of anticoagulant therapy. We fixed Stentless Xenograft in evert mattress fashion in the same way by mechanical valve conduit fixation. We evaluated our new method in twenty-one patients underwent aortic root replacement. The diagnosis of all the patients was annulo-aortic ectasia. In the wrapping group (n=6) aortic cross-clamping time was significantly shorter, operation time and ICU stay were longer and intra-operative bleeding loss were lesser than these in open (n=15) method. In Stentless Xenograft group (n=6) the patients were significant older, aortic cross clamping time was longer. ICU stay and hospital stay after surgery were shorter than these in mechanical valve group (n=15). Our new series with Stentless Xenograft in evert mattress fashion was better than traditional wrapping method. |
